Yo is a diminutive, mythical creature known as a Meek. She lives snuggled up inside the ear of a giant, floating jelly fish mountain. Mostly shunned or shouted at by her own kind, simply for being different, she finds herself thrust onto a perilous adventure to save the meekle and their home, Jelly Mountain. It's not something she really wants to do, but a series of events continuously leave her with no option other than to struggle onward. Along the way she encounters friends and enemies, who try hugging, squashing, eating, saving and sucking the life out of her. All the while it's a race against time to get back to Jelly Mountain, before her, rather inadequate leaders do something particularly stupid. But will she make it back in time? Save the mountain, and the meekle? More importantly, will anyone really care?
